How Do Snakes Adapt To Their Environment?

Several ways.  For instance.  A lot of snake don't hibernate.  But when it gets cold then their body slows down enough that they don't have to move much.  Sometimes all winter long.  If their food becomes scarce then their metabolism slows down.  Sometimes dramatically.  The record is over two years that a snake survived without eating before it starved to death

they are cold blooded and can survive for 2 years without food and not starve to death
